But to re-re-state the issue I initially raised for discussion (on this
thread):

The M8 data flow appears to be

CCD Chip 14bits -> padded with 2 bits to make 16bits -> 'square root
compression' -> 8 BIT NON-linear DNG file -> computer --> 8 BIT DNG
re-expanded to 16 Bit Image file (typically a TIFF file).

The LFI article does imply that while there is some loss, that it is
imperceptible.

?
